\begin{document}$J/\psi$\end{document} and \begin{document}$\phi$\end{document}) is investigated by considering the next-to-leading order corrections in the framework of the color glass condensate. We compare the next-to-leading order modified dipole amplitude with the HERA data, finding a good agreement. Our studies show that the \begin{document}$\chi^2/d.o.f$\end{document} from the leading order, running coupling, and collinearly improved next-to-leading order dipole amplitudes are 2.159, 1.097, and 0.932 for the elastic cross-section, and 2.056, 1.449, and 1.357 for the differential cross-section, respectively. The results indicate that the higher-order corrections contribute significantly to the vector meson productions, and the description of the experimental data is dramatically improved once the higher order corrections are included. We extend the next-to-leading order exclusive vector meson production model to LHC energies using the same parameters obtained from HERA. We find that our model provides a rather good description of the \begin{document}$J/\psi$\end{document} and \begin{document}$\phi$\end{document} data in proton-proton collisions at 7 TeV and 13 TeV in LHCb experiments."> Exclusive photoproduction of vector meson at next-to-leading order from color glass condensate -
